Inverting Amplifier

The inverting op-amp or operational amplifier is an essential op-amp circuit configuration that uses a negative feedback connection. As the name suggests, the amplifier inverts the input signal and changes it. An inverting op-amp is a type of operational amplifier circuit used to generate an output that is out of phase as compared to its input through 180 degrees which means, if the input signal is positive (+), then the output signal will be opposite. The inverting op-amp is designed through an op-amp with two resistors.
